    EL WIRE---if you know anything about it click here!!!URGENT...sorta

    I was going to see if I could find a short in the wire so I hooked it up then was gone bend the wire abound a much as I could given it was attached down to my pannel.

    EL WIRE---if you know anything about it click here!!!URGENT...sorta

    I hooked up a brand new inverter and the same wire didn't work.  I used the wire to line the edges of the panel of buttons for a project of mine.  It gets used in the dark and this is an impressive way to light it.  The wire is bent about the corners fairly sharply.  How does the wrap wire short...

    EL WIRE---if you know anything about it click here!!!URGENT...sorta

    Quick question:  I ran 1.5V more than recomended (at 1A besides ::)) into an inverter driving EL wire.  It was also only about 1/4 of the length of wire that came with the inverter.  It caused the TV in the room to go all fuzzy (didn't happen with a smaller power supply or the full length) and...

    Speaker wire question

    So if I have a resistance of .7ohm thats too much?  How much distortion will that cause?

    Speaker wire question

    I have some extra speaker wire from a long time ago and I don't know the AWG.  I need to extend two 70W 4ohm speakers about 16ft. and 10ft.  One is about twice the size of the other but same wattage.  The provided speaker wire is a larger AWG than the extra I have but I also don't know it's...

    driveway monitor

    I need to make a driveway monitor that blasts a piezo indoors when someone comes in the driveway.  (I am making this for someone) their driveway is maybe 1000ft. long  or so.  I figure I could have a IR led powered with a 555 and bateries on side and the other side could have the IR photo...

    LED amperage question

    They way the system is there are several positives to multiple nichromes and one negative and the LED and push button is on the negatove side.  Therefore, pushing the buttons (the multiple ones) does a continuity test but if you hold down the one button and press one of the others causes a fire...

    LED amperage question

    Sorry I should have wordered the questions differently.  I was meaning when 13.5V @ 1A with the right resistor is applied to a LED what is the resulting mA comming out of the - lead? About the pushbutton:  What I meant was a SPST NO pushbutton wired in parallel with the LED and resistor.  Would...

    LED amperage question

    I have a quick question and Ill delete this topic after I get an answer.  How many mA do I get out of a LED?  The same ammount as it draws?  Less than that?  Or supply minus the draw?  The max supply I may have is 13.5V @ 1A.  I am using a LED as an indicator(with a proper resistor) of a...

    Schematic program

    What program does everybody out there use to make their schematics?  I have been using CircuitMaker Student (demo) and I can't have more than 50 components.  I need get a good probram that isn't a demo.

    Quick AC question

    I live in the US and the cord I bought has just 2 plugs--the left on is bigger and I think is the neutral.  Anyone know this for sure?  The other end is just bare wire but I can just follow the side of the wire down to the end.

    Quick AC question

    Well i have a wall plug that I bought--how do I know which is the hot wire?

    Resistor wattage

    I need a 80 ohm resistor at 1.1 watts.  When you combine reisistors in series does the wattage combine.  So would two 40 ohm 1/2 watt resistors in series be equal to 80 ohm 1 watt instead of using a power resistor? Thanks

    Quick AC question

    I'm sorry I have to ask such a dumb question but every othere resourse is eplaining how to uses caps and resistors in AC and can't (to a full extent) answer my question. I can't figure out what AC is.  I know what it stands for and that it goes at 60Hz.  I used to think there was a positive and...

    Simple remote gopher

    Couple questions: If I want to make infrared filters (blocking visible light) I need to get unexposed but developed film? right?  And you use 2 layers? Is the voltage going to the LEDs (the red and the IR) affected by the opamp (I dont really know anything about them)?  So if i want to use more...

    Simple remote gopher

    Being new to electonics I need some advice on building a very simple remote extender. I don't know very much about IR (well I'm certainly starting to in other research) or in using transistors and signal recievers. My seperate question: When you are using a reciever such as an IR one..it has to...

    Simple LED strobe

    I'm designing something.  Not sure what.  :o ??? Sort of.  OK nevermind that. I'm still new to electronics and somehow have trouble with 555.  I think I need to spend a day to just figure them out.  Anyway, I need an astable circuit that wil cause LED(s) to blink that can be adjustedd by a...

    Long distance car sensor.

    Sorry I haven't replied lately.  Because they have to work at night the camera might not work because the infra-red won't cover enough distance. (I need several hundred feet of coverage.)  Plus that would be expensive and the Nebraska weather will wear away at camera even if it's weather proof. ...

    BENCH POWER SUPPLY

    Hmmm well it's not done.  Have been really busy with school and I'm just taking a break from the project.  At first I was thinking "where did all my messages go?"  I continued with this project in the board meant for the LM317 supply and I can't remember if you had made any replies in there or...
